Gov. Bobby Jindal once again relegated to undercard at Oct. 28 presidential debate on CNBC

The field of 10 candidates appearing in the main GOP presidential debate to be held Oct. 28 on CNBC. Gov. Bobby Jindal had objected to the network's criteria, arguing his performance in Iowa (which is better than his national poll rankings) ought to be considered.

Despite Gov. Bobby Jindal's objections, he has once again been limited to another GOP presidential debate "undercard" — this one set for Oct. 28 at 5 p.m. New Orleans time on CNBC.

National polls will be used to determine a candidate's eligibility and placement on the stage. To be eligible to appear in either segment, a candidate must have at least 1% in any one of the methodologically sound and recognized national polls conducted by: NBC, ABC, CBS, Fox, CNN and Bloomberg, released between September 17, 2015 and October 21, 2015.

To appear in the 8pm debate a candidate must have an average of 3% among these polls. The polls will be averaged and will be rounded up to 3% for any candidate with a standing of 2.5% or higher. Candidates who average below that will be invited to the 6pm debate.

Jindal's argument — that CNBC should weigh polling numbers from Iowa and New Hampshire — went nowhere with the network, and in recent days the campaign had intimated Jindal might skip the debates entirely if he was not offered a slot in the main debate. The governor has averaged 1 percent or less in most national polls, but a RealClearPolitics poll conducted in late September showed him in eighth place in Iowa with 4 percent support — in that state, ahead of Kentucky Sen. Rand Paul, New Jersey Gov. Chris Christie and Ohio Gov. John Kasich, all of whom will be on the main stage at the CNBC debate.

If he accepts, Jindal will share the podiums at the second tier debate with former Pennsylvania Sen. Rick Santorum, former New York Gov. George Pataki, and South Carolina Sen. Lindsey Graham. The debates will air live from Boulder, Colorado.
